SOUTH SAN FRANCISCO, Calif., May 03, 2023 (GLOBE NEWSWIRE) -- Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer, today provided a corporate update and reported financial results for the quarter ended March 31, 2023.
“Our first quarter progress continues to establish Allogene as the leader in the development of allogeneic CAR T product candidates,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “Our success across multiple clinical programs, ability to attract top tier talent, and financial stewardship to weather the challenging external market environment paves the way toward to bringing a new generation of CAR T products to patients.”
Pipeline Updates
ALLO-501A: Anti-CD19 AlloCAR T Program
The Company continues to enroll patients in the industry’s first potentially pivotal Phase 2 allogeneic CAR T clinical trial with ALLO-501A. The single-arm ALPHA2 trial is enrolling patients with relapsed/refractory (R/R) large B cell lymphoma (LBCL) and utilizes a single dose of ALLO-501A (120 million CAR+ cells) following lymphodepletion with FCA90 (fludarabine, 30 mg/m2; cyclophosphamide 300 mg/m2; and ALLO-647 30 mg, daily for 3 days). This trial will enroll approximately 100 patients who have received at least two prior lines of therapy and have not received prior anti-CD19 therapy. The primary endpoint is overall response rate (ORR), and the key secondary endpoint is duration of response (DoR). Patients may receive treatment as an outpatient at the investigator’s discretion. The Company expects to complete enrollment in 1H 2024.
During the first quarter, the Company initiated the EXPAND trial to support licensure of ALLO-647. The Company is developing ALLO-647, an anti-CD52 monoclonal antibody, to permit the use of standard low-dose FC (fludarabine, 30 mg/m2 and cyclophosphamide 300 mg/m2, daily for 3 days) lymphodepletion regimens across our portfolio. This proprietary regimen is intended to prevent premature rejection, thereby enabling expansion and persistence of AlloCAR T cells and supporting improved clinical performance of product candidates. In the EXPAND trial, approximately 70 patients with R/R LBCL will be randomized to be lymphodepleted with FCA90 (which includes 90 mg of ALLO-647) versus FC alone before receiving a single 120 million cell dose of ALLO-501A. The study is designed to demonstrate the superiority of FCA90 over FC as measured by progression free survival (PFS).
After the close of the quarter, the Company announced that pooled data from the Phase 1 ALPHA/ALPHA2 trials of ALLO-501/501A, in R/R LBCL would be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting June 2 – 6, 2023 in Chicago, Illinois.
ALLO-316: Anti-CD70 AlloCAR T Program
The Company presented interim data from its Phase 1 TRAVERSE trial of ALLO-316, the Company’s first AlloCAR T investigational product candidate for solid tumors, during an oral presentation at the American Association for Cancer Research (AACR) Annual Meeting in April.
The ongoing dose escalation study is enrolling patients with advanced or metastatic renal cell carcinoma (RCC) who have progressed on standard therapies that included an immune checkpoint inhibitor and a VEGF-targeting therapy. Emerging data from this trial have demonstrated the potential of an allogeneic CAR T product to treat CD70 expressing RCC. In this trial, ALLO-316 showed early anti-tumor activity with deepening responses over time. The data reported to date is primarily from the DL1 and DL2 cohorts.
Anti-tumor activity was primarily observed in patients with tumors confirmed to express CD70 (N=10). Among 18 patients evaluable for efficacy, the disease control rate (DCR) was 89%. In the 10 patients whose tumors were known to express CD70, the disease control rate was 100%, which included three patients who achieved partial remission (two confirmed, one unconfirmed). The longest response lasted until month eight. There was a trend toward greater tumor shrinkage in patients with higher levels of CD70 expression.
In patients evaluable for safety (N=19), ALLO-316 demonstrated an adverse event profile generally consistent with autologous CAR T therapies. One dose-limiting toxicity of Grade 3 autoimmune hepatitis occurred in the second dose level. Cytokine release syndrome (CRS) was all low-grade with the exception of one Grade 3. Neurotoxicity, which is now defined more broadly, was generally low grade and reversible with most events being fatigue or headache. There were no cases of immune effector cell-associated neurotoxicity syndrome (ICANS). Infections occurred in eight patients of which four were Grade 3+ including one Grade 5 respiratory failure due to Covid-19 infection deemed unrelated to study treatment. Grade 3+ prolonged cytopenia was observed in three patients (16%). There were no cases of graft-versus-host disease (GvHD).
The Dagger™ technology, which is a feature of ALLO-316, is designed to resist rejection of AlloCAR T cells by the host immune cells, thereby supporting expansion and enabling a prolonged window of persistence during which AlloCAR T cells can target and destroy cancer cells. Initial translational data from the TRAVERSE trial demonstrates the suppression of CD70 positive, alloreactive host T cells and marked peak expansion of ALLO-316 despite the relatively low cell doses tested. The Company plans to deploy Dagger technology to potentially enhance the persistence and activity of next generation AlloCAR T products, including those that target other hematological and solid tumors.
The Company has deployed a new investigational in vitro companion diagnostic (IVD) assay designed to prospectively assess CD70 expression levels to enhance patient selection. Dose escalation in the TRAVERSE trial is expected to be completed in 2023.
ALLO-715: Anti-BCMA AlloCAR T Program
During the quarter, data from the Phase 1 UNIVERSAL trial with ALLO-715 for the treatment of r/r multiple myeloma (MM) was published in Nature Medicine. UNIVERSAL is the first allogeneic anti-BCMA CAR T to demonstrate proof-of-concept in MM with response rates that are similar to an approved autologous CAR T therapy. The Company is evaluating manufacturing processes improvements across its BCMA candidates to achieve optimal performance.
Corporate Updates
In April, it was announced that Timothy Moore had been appointed as Executive Vice President, Chief Technical Officer. The appointment of Mr. Moore, an industry pioneer responsible for the global development of two of the most commercially successful autologous CAR T manufacturing processes, reinforces the Company’s focus on being the first to bring an AlloCAR T product to market.
